What does wet pressed ferrite mean? Main uses of wet pressed arc ferrite

What does wet pressed ferrite mean? Where are wet-pressed arc ferrites mainly used? The following article will focus on this issue to share with you.

Sintered ferrite magnets are mainly divided into dry pressing and wet pressing. Today, we mainly talk about wet pressing, and we will introduce dry pressing in detail later. Wet pressing means that the molding slurry contains water, and the particles formed in the magnetic field are easy to turn, so it is easier than dry pressing. The higher the degree of orientation, the higher the magnetic properties, and the more stable it is.

Introduction of ferrite wet pressing process;

In the ferrite magnetic field molding process, the wet pressing molding process is to place the slurry after secondary ball milling directly in the mold, and at the same time apply a certain direction (consistent with the magnetic field direction required when the product is used) during pressure molding. In the strong magnetic field, the easy magnetization axes of the single domain grains are aligned along the direction of the external magnetic field. At the same time, a pump should be used to remove moisture, and spacers should be used at the upper and lower punches to prevent the slurry from being drawn out, and then dried after molding. In wet pressing molding, due to the high moisture content of the slurry, the grains can rotate freely during the molding process, which is convenient for grain orientation, so the magnetic properties are good, and the Br is large and the Hcb is high. However, gaskets and suction filtration are required during molding, and the production efficiency is low.

Main uses of wet-pressed arc ferrite;

Wet-pressed arc-shaped ceramic magnets are the core components of permanent magnet micro-special motors. They are generally used as motor stators and are mainly used in various motors such as automobiles, motorcycles, home appliances, power tools and fitness equipment. The most widely used ones are automobiles and motorcycles. Vehicle and inverter home appliance industry. Such as car starter motor, ABS motor, purification fan motor, heater motor, seat motor, window motor, speed control stepper motor, treadmill motor, ceiling fan motor, DC inverter washing machine drum motor, air conditioner, refrigerator compressor motor, etc. .
